Call me old school but I'm not in constant possession of a selfie stick. Knowing how to ask someone to take a photo seems like the next best thing.
French: Pouvez-vous prendre une photo?
Spanish: ¿Podrías sacarme una foto?
Arabic: هل يمكنك التقاط صورة؟
Mandarin: 可以帮我拍照片吗? [Pinyin: kě yǐ bāng wǒ pāi zhào piàn mǎ?]
English: My Facebook needs a facelift.
